12. What are the ideal -Lots of nonpoint source emitters
physical conditions
-Lots of sunlight (UV radiation)
for photochemical
-Favorable topography (barriers for wind current)
smog to develop in
-Daily temperature inversions (high temperature contrast)

13. What are the
Carbon monoxide, nitrogen monoxide, and RH.
prima- ry
pollutants in
photo- chemical
smog?
Hydrocarbons, nitrogen dioxide, and ozone.
14. What are the sec-
ondary pollutants
in photochemical
smog? Secondary pollutants are produced as a result of primary
pollutants' concentration and atmospheric conditions.
15. When and how Peaks in LA
are the secondary NO2: occurs from 9am-12pm, after peak concentration of primary
pollu- tants pollu- tants.
produced in the Ozone (O3): occurs from 12pm-3pm.
daily smog cycle? PAN: occurs around 12pm, after peak concentration of primary
pollu- tants.
No primary pollutants are present in the evening due to the land
breeze.
